Final answer:
The demand for a healthy menu from restaurants due to obesity concerns is more related to a shift in consumer preferences, influenced by health consciousness, rather than a demographic force. Factors like increased physical activity and availability of healthier food options can limit obesity.
Step-by-step explanation:
The demand for a healthy menu from restaurants due to obesity issues is not primarily a demographic force, but rather a shift in consumer preferences. A demographic force would be changes related to the characteristics of a population, such as age, race, gender, income level, and education. While it is true that demographic factors can influence obesity rates, the change in menu preferences is more directly related to a social trend towards health consciousness and the impact of lifestyle choices on health outcomes like obesity that has resulted in type 2 diabetes.
Factors that may limit obesity include increased physical activity, education on healthy eating, availability of healthier food options at lower costs, and public health initiatives aimed at reducing sedentary behavior and improving overall health awareness.
